Abstract

The efficacy of the preservative chemicals for the treatment of wood samples was evaluated in ground contactagainst termite and fungus. The wood samples treated with boric acid followed by maleic anhydride, copperacetate, sodium salt of diethyldithiocarbamate and kerosene showed higher dimensional stability efficiency interms of anti-shrink efficiency (ASE), bulk co-efficient (BC) and weight percent gain (WPG). The treated woodsamples showed higher strength properties such as modulus of rupture (MOR) and modulus of elasticity (MOE)than the untreated sample. The treated samples could resist from termite and fungal attack and also extend theservice life.
